Different versions of python can be a mess to deal with, also, at least
with respect to standard modules being "standard" or not for a specific
In any case, the point is that we try to avoid *additional*
dependencies. Shell and perl are given with the status quo.
That being said, we also have remote helpers in python. The testsuite
can run tests depending on the availability of python.
Regarding git-weave, I'm wondering (without having looked at the code)
how this relates to git-archiv and git-fast-import/export, i.e. how much
this leverages existing infrastructure rather than reinventing the
wheel. Do your "trees" correspond to a "git tree"?
Again, without having looked at the code, it seems to me that exploding
blob and tree objects might give you a structure not much unlike
weave's, and your instruction sheet resembles that of fast-import quite
a bit (plus date fill-in etc.).
One could even dream about implementing this as a remote helper instead...
